Add setup arguments to enable specifying alt tenants on the CLI (#900)

This enables specifying the endpoint configuration for alternate tenants purely on the command line.

Previously, on a single tenant you could use the following:
```
onefuzz --endpoint https://INSTANCE.azurewebsites.net info get
```

For multi-tenant installs, we need to expose more than just endpoint.

This enables:
```
onefuzz --endpoint https://INSTANCE.azurewebsites.net --client_id CLIENT_ID  --authority https://login.microsoftonline.com/common --tenant_domain TENANT_DOMAIN info get
```
